The Imperial Ecodriver 4 model is an excellent choice for drivers of passenger cars. Its asymmetric tread has two tasks: the inner side effectively drains water, while the outer optimizes grip, even in high-speed corners. The 3 circumferential grooves improve traction on wet roads and ensure almost instant braking in difficult conditions. The numerous cuts and transverse grooves quickly dry the tire and minimize the risks of aquaplaning. A new silica compound reduces rolling resistance and improves traction on wet ground. The shoulder block design minimizes noise levels.
